on one side and house No. 4 on the 

 other side, to 60 degrees in zero weath- 

 er? All these houses have glass in 

 one end to within three feet of the 

 ground. We shall use low pressure 

 steam for heating. Our location is 

 southern Indiana. M. A. B. 



For house No. 1 use two 2-inch flows 

 and six 1-inch returns. In house No. 

 2 use two 2-inch flows and five or six 

 1-inch returns. Using 2-inch pipe for 

 returns as well as flows in house No. 3, 

 two flows and three returns will be re- 

 quired. Two 2-inch flows and four 2- 

 inch returns will be required in house 

 No. 4. There should be two 2-inch 

 flows and five 2-inch returns in house 

 No. 5. It will not be necessary to 

 use anything larger than 2 1^ -inch flow 

 pipes for any of the houses. 



BETUBNma THE CONDENSATION. 



We have an old-style heating system, 

 with a wet return and with no checks 

 on the lines, and should like to know 

 about installing a trap. It is a gravity 

 system, with the boiler in a pit. Would 

 a check on the main return to the 

 boiler work? We have 20,000 feet of 

 glass and should like to know what size 

 of trap would be needed. L. B. 



If there is any difficulty about re- 

 turning the water to the boiler by the 

 gravity system, a steam trap should be 

 installed. It is always well to have a 

 check valve on the main return when 

 several houses are heated from one 

 boiler. As to the size of trap you 

 would need, the various forms of traps 

 differ in their capacities. It will be 

 well to consult the manufacturers who 

 are advertising in The Eeview. In 

 writing to them, state your amount of 

 radiating surface and the steam pres- 

 sure carried. 



PIPINa AN OmO BANQE. 



I am building a greenhouse, seventy- 

 five feet long and twenty-nine feet 

 two inches wide. I wish you would 

 kindly inform me how to heat it, us- 

 ing hdt water. About one-half of the 

 stock will be benched, the rest on the 

 ground. I have a boiler 10x4x8, con-
